Points to note about LED lights

First look at the chip
The chip is the core light-emitting element of the LED lamp, and the luminous efficiency and color rendering index of different brands and models of lamp beads are different. Most of the lamps on the market now use single crystal chips, and integrated chips are also called COB chips, which have better performance than single crystal chips. Therefore, when purchasing, try to choose COB chips, which not only have a long service life, but also have higher luminous efficiency and color rendering index, and they are used in a wider range of situations.
Second look at the color temperature
Different lighting places, such as bedrooms, living rooms, kitchens and bathrooms, have different needs for lighting. At this time, you can look at the color temperature of the Led lamp to choose. The color temperature range of LED lights is 2700~6500K, the smaller the value, the yellow light, otherwise, the blue-white light. The color temperature range of suitable LED lighting fixtures should be close to the color temperature range of the natural white light of the sun. It is a scientific choice. In daily home lighting fixtures, you can choose 2700K incandescent lamp color or 5000K neutral white; in addition, the light is not as white as possible. Lights with high color temperature are close to the glare at noon and are too irritating to the eyes, while low color temperatures are prone to fatigue. Only lights with a comfortable color temperature are healthy lights.
Third look at luminous flux
Luminous flux generally refers to brightness. Different environments and different areas require different light. Under the same number of pings, the number of bulbs used is different according to different environments. When buying, you can consult the shopping guide according to your own space needs. When choosing a lamp, it is necessary to combine the lighting environment, refer to the luminous flux index of the product, or pay attention to the brightness of the light, and try to choose a lamp with sufficient brightness but not dazzling.
Fourth look at the color rendering index
To look at the color rendering index is to look at the true degree of the color of the object under the light. The value is generally 0-100. Now the color rendering index of LED bulbs is greater than 75, and it is recommended to choose more than 80.
Fifth, perform stroboscopic test
It is recommended to check whether the purchased LED lamps are stroboscopic. The stroboscopic lamps will affect the eyesight. Stroboscopic is a problem that is difficult to detect with the naked eye. You can use your mobile phone to aim at the illuminator to take pictures. If the photo appears gray and white "striped", it means there is stroboscopic, if there is no "striped", it means there is no stroboscopic
